Can you use pistol power in 7.62x39 loads to create basically bootleg 300 blackout for mini AKs?

idk try it
Yes if VERY careful.
Anon if you're using a sub 16" AK you already have a bootleg .300blk, especially if you just shoot cheap ass target steel case. Unless you wanna be moronic then just CFEBLK
Absolutely fricking not
Chamber pressure would cause you to lose your hand.
Why would the chamber pressure be so much higher in 7.62x39 if you use the same powder charge? The projectile is of similar size and weight and the casing actually has more volume.
That ain't pistol powder in those rounds. Pistol powder grains are tiny, so much more of the surface area is exposed in the same size loads. This results in a MUCH more rapid pressure spike.. A spike rifle chambers and barrels are NOT designed to deal with. Pistols have much shorter barrels, so before the spike can get crazy, the round is out and pressure drops. But that's also why pistol pressure spikes need to be so fast, the much shorter time a pistol has to accelerate the projectile. Besides, .300 blackout in anything above subsonic makes no fricking sense for what it's designed to do: It's ultimately an assassin's weapon. Silent, with a bit more standoff than a suppressed .45acp.. But I see it as an abysmal failure. Hell, I'm getting WAY better performance out of a .338 Federal with super heavy custom projectiles through a can. Then just swap back to 7.62X51 on the easy on/off barrels. But hey, you do you.
>Pistol powder grains are tiny
not always, there's a lot of overlap between the range of sizes you find in pistol powders and the range of sizes you find in rifle powders
>much more of the surface area is exposed
flame moronant coatings and the shape of the granules also have a massive impact
He said power not powder. I thought the same thing at first.
>yeah bro 7.62x39 is just like outdated need modern gucci shit for my ar gays
>WHOA IS THAT HECKING .300 BLACKOUT
>7.62x35
>yeah its basically the greatest round ever made
300 blackout gays are moronic and reinvented a 70 year old cartridge congrats
>changing the dimensions of a venerable cartridge slightly so a new round doesn't chamber in a gun designed for the old rounds, then increasing pressure significantly in the new round
Bullet designers do this all the time. It's basically just for liability so that ammo sellers can make powerful rounds for modern guns without blowing up some fudd's cheap replica and getting sued over it.
The problem with x39 in an AR is the larger case head requires a thinner bolt to fit in the AR chamber, which results in it being more fragile. 300 blackout uses the same bolt as 5.56 which sidesteps the issue.
>take one of the best cartridges ever designed
>solve some slight design incompatibilities making it actually work in one of if not the best rifle designs ever created
>you can even reload it by mixing and matching extremely popular cartridge components
pretty sure youre the moronic one.
1. NO.
2. Are you really that fricking stupid that you don't know what burn rate is?
3. Do you really not realize that .300 Blackout exists to DUPLICATE 7.62x39 in AR-15?
This post is probably bait but It's so incredibly stupid I have to comment.
I just don't understand why the pressure would be too high if you have the same powder charge and almost the same projectile in a slightly larger case. The higher burn rate would be the entire point—getting more effect out of short barreled AKs.
Higher burn rate means that the pressure generated spikes long before it's supposed to, essentially creating a pipe bomb.
>Higher burn rate means that the pressure generated spikes long before it's supposed to
this isn't a problem as long as the pressure at that spike is no higher than the peak pressure in the normal rifle cartridge.
Yea if you loaded it properly you can absolutely make a 7.62x39 bootleg of .300 BLK. If anything thats a bit of a weird question considering subsonic 7.62x39 is very much a thing and was widely experimented with in soviet times by far predating .300 BLK. Long story short was that the soviets found that the window of maintaining reliable subsonic(instead of going super sonic occasionally) performance while maintaining reliability with an AK type platform was too hard. Hence the 9x39mm. With a bit of tinkering im sure you could get an AKM to more or less clone .300 BLK performance and work reliably, the only problem would come in if you want the thing to work reliably and stay subsonic whether its an midwest summer or an alaskan winter.
I realize this is probably an even more niche idea than wanting a better subsonic load, but I was more interested in the idea of maximizing effectiveness out of short barreled AKs while minimizing concussion and mostly doing this with supersonic ammo.
Okay I get that this is the general problem with too fast burning of a powder. What I'm just not understanding is why it does work in 300 Blackout if it won't work in 7.62x39.
1. Not all barrels are rated for the same level of pressure, a .30 Supper Carry is rated for twice the pressure as a 9mm barrel, for example.
2. .300 blackout doesn't use fricking pistol powder.
It does. H110 is one of the most popular powders used in it. Most of the magnum pistol powders are suitable.
The primary powders used are CFE Black and IMR 4227. If you're using pistol powders you're sticking to light subsonic loads because too much of that shit is dangerous, which entirely beats the point of .300 blackout, which is to duplicate 7.62x39.
You may actually want to do some reading on it.
Well could you load 7.62x39 with one of those powders, then?
everyone thinks you typo'd "power" and meant "powder", OP. Sub-sonic is the term you want, and sub-sonic 7.62x39 already exists and is commercially available
sure. it's was pretty common back in the day to download 308 Win and 30-06 to 1200fps or so using pistol powders for plinking at cans or shooting at coyotes. get a copy of quickload and play around with it, you'll probably want slower pistol powders, but I don't really know which ones would be best. I'd plug in VV 3N38 and Hodgdon Lil Gun into quickload and see how they do, and work your way out from there. you'll have the additional challenge of getting enough port pressure to work the action. are there any adjustable gas systems for AKs? that would help quite a lot.
x39 is already loaded with stupidmoron fast powder
wolf chronos at 2500 fps outta an 8" barrel
What? You aren’t getting any more than 2400 fps with 60 gr Wolf through an 8” barrel
60 grain?
x39 is 123ish grain bullets bro
What are you talking about dumbass?
that is 5.45
when left to implication, it's always a 7.62, bro, like how you just say 54r when talking about nugget food or x25 when talking about tokarev food
Only morons say that. Pull your head out of your ass.
been saying it since x25 was under 10 cents a round, kiddo
went and looked at my notes, it's actually 2200
whoops
You could experiment with it until you got it to reliably cycle and see if it was doing what you wanted with the amount of powder it takes to cycle it.
